The display culminated in the arrival of team's 2013 drivers, Jenson Button and Sergio 'Checo' Perez.

"The MP4-28 (new car) isn't merely a refinement of last year's seven-race-winning car, it's a deep and sweeping re-design of an already successful chassis in several key areas - most notably around the nose and front suspension, the sidepod profiles and the rear bodywork," said McLaren in a release.

Jenson begins his fourth season at McLaren as the team's most experienced driver. During his time here, he has won more races (eight) and scored more points (672) than during the rest of his 10-year Formula 1 career.

By contrast, Checo is starting only his third season in F1. Young, eager to learn, and already impressing the team with his ability to absorb information, the 23-year-old is perfectly poised to benefit from the team's experience as he develops and gathers pace during his important first season here.

Jenson will begin track testing of the MP4-28 at Spain's Circuito de Jerez Feb 5.
